Percent vs Dollars vs Free Shipping: Framing Changes Behavior, Not Just Math
Unico Commerce, FounderPercent vs Dollars vs Free Shipping: Framing Changes Behavior, Not Just Math
A 10% discount and its dollar equivalent are the same money. They are not the same message. Shoppers process them differently, trust them differently, and act on them differently — and the right frame depends on the basket, the blocker, and whether the claim survives scrutiny.
Framing is not deception. It is translation: the same concession expressed so the shopper can feel its size accurately. The line is crossed only when the frame invents value — inflated was-prices, resetting timers, fees revealed late. Keep every frame provable and the advantage is fully legitimate.
The working heuristics — tested, not assumed
Small baskets read dollars; large baskets read percents. The long-standing Rule of 100 captures it: below roughly $100, a dollar figure feels concrete ($10 off reads larger than 10% off $80); above it, the percentage carries the weight (20% off $300 beats "$60 off" in attention, even at identical value). Treat it as a starting hypothesis per category and test it — framing effects vary by price familiarity and margin structure.
Shipping frames remove surprises; percentages don't. When the blocker is extra-cost shock at checkout — consistently the top abandonment reason in Baymard's surveys — free or reduced shipping attacks the cause while a percentage merely softens the total. A shopper angry about a $9 fee is not mollified by 10% off the product; they are converted by the fee disappearing.
Gifts frame as gain; discounts frame as reduced loss. A threshold gift reframes the task from "pay less" to "get more," which suits hesitant-but-warm shoppers better than deeper cuts. Price the gift at true cost (product plus handling) against the percentage it replaces — gifts often cost less per incremental order than they appear to.
Compliance is part of the frame
Every frame must survive the audit that regulators now expect: reference prices real and recent (the EU's lowest-prior-30-days rule for was-prices), urgency that actually expires on inventory that exists, shipping and fees disclosed before payment. A frame that needs an inflated anchor or a fake timer is not a frame — it is a misrepresentation with a conversion rate.
Keep a timestamped price ledger so any was-now claim is provable on demand. If the anchor cannot be proved, the frame cannot run.
Test frames like depths: laddered, held out
For one hesitation moment, test frames at equal economic cost: 10% vs. its dollar equivalent vs. shipping relief vs. threshold gift. Measure incremental contribution per eligible visitor, not click-through — the flashiest frame often wins attention while losing margin. The winner is the cheapest frame that clears the specific blocker, which is why blocker diagnosis precedes frame choice.
The takeaway
The same money converts differently in different words — and the cheapest effective frame usually isn't a percentage.
Diagnose the blocker, match the frame to basket and cause, keep every claim provable — then test equal-cost frames against a control and keep the one that adds contribution, not clicks.
Framing every offer as a percentage? Connect your Shopify store and Unico will match frame to blocker — dollars, percent, shipping, or gift — at equal cost, tested for incremental contribution.
